PURPOSE:To improve work efficiency by placing a magazine for storing a plate material like a lead frame on a magazine holder capable of moving up and down and transferring the magazine onto a discharge table with the above holder and discharging same, so that the magazines are supplied and discharged by severals. CONSTITUTION:Magazines 15A, 15B for storing lead frames 17 are placed on a conveyer 60. When the conveyer apparatus is started, the magazine A is transferred onto a magazine holder 16 to be held by vacuum force working upon an adsorption hole 16a. Subsequently, a push-out lever 41 is reciprocated through a shaft 44 and so on by the rotation of a motor 43 to fed out the lowermost lead frame 17. After that, a holder 16 is lower by a feed screw 20 rotated by a motor 21, and when the second slit 30a from the bottom of a position detecting plate 30, the lowering movement of the holder is stopped to fed out the second led frame 17. After all lead frames 17 in the magazine 15A are fe out by repeating the above operation, the mgazine 15A is discharged to a discharge table 66. |
